* Elves in Northern Lore: Elves in Norse mythology (Northern Lore) are typically described as beautiful, graceful, and powerful beings. They are often associated with nature, magic, and the arts. They are not typically depicted as "tubby" or "senior."
* Possible Misunderstanding: It is possible that you are thinking of a character from another source, such as a fantasy book or movie, or a modern interpretation of elves.
If you can provide more context or information about where you encountered this "tubby senior elf," I may be able to help you further.
